    • Method of fabricating an cold cathode for a laser such as ring laser gyro characterized by the use of vitreous carbon as the material of the cathode. For this purpose a predetermined amount of resin is pressed formed into the shape of a hollowed cathode body which is then heated in an oxygen free environment form a vitreous shaped cathode by thermal degradation of the resinous body. The vitreous carbon material reduces the difference between the coefficients of thermal expansion of the housing and electrode which can cause the indium seal to fail, e.g., in the case of prior aluminum cathode. The electrical connection may be made via either a silver epoxy or indium solder.
    • 制造用于诸如环形激光陀螺仪的激光器的冷阴极的方法,其特征在于使用玻璃碳作为阴极的材料。 为此,将预定量的树脂压制成中空阴极体的形状,然后通过树脂体的热降解在无氧环境中加热形成玻璃态阴极。 玻璃碳材料减少了壳体和电极的热膨胀系数之间的差异,这可能导致铟密封件失效,例如在现有的铝阴极的情况下。 电连接可以通过银环氧树脂或铟焊料制成。
